Infineon Technologies IRSM636-015MB

Overview

IRSM636-015MB from Infineon Technologies is a fully integrated intelligent power module (IPM) containing six 600 V, 15 A IGBTs with integrated gate drivers, bootstrap diodes, and protection circuitry in a single 27-pin DIP package. It implements a 3-phase inverter stage for motor control, supports 15 kHz PWM switching, and delivers continuous output current up to 15 A at T_c = 80 °C. It is used in HVAC blower drives and industrial servo inverters.

For engineers reviewing the IRSM636-015MB datasheet, IRSM636-015MB pinout, IRSM636-015MB application, or IRSM636-015MB equivalent, key selection criteria include integrated short-circuit protection response time, built-in overtemperature shutdown threshold, bootstrap diode forward voltage drop, and phase-to-phase isolation rating.

Technical Context

The IRSM636-015MB integrates six N-channel IGBTs in a 3-phase bridge configuration with matched gate drive timing and cross-conduction prevention logic. Its embedded protection includes desaturation detection with 2.5 µs response, under-voltage lockout on both high-side and low-side supplies, and thermal shutdown at 150 °C with hysteresis.

It uses a monolithic driver IC with level-shifted high-side outputs and supports 3.3 V/5 V logic-compatible input signals. The module's internal bootstrap circuit eliminates external high-side floating supply components while maintaining >100 V/ns common-mode transient immunity.

Key Specifications

Pinout & Package

IRSM636-015MB is housed in a 27-pin dual-in-line package (DIP-27) with creepage/clearance optimized for 300–400 V AC systems. Pin layout supports separate power and signal ground returns, isolated bootstrap paths per high-side leg, and dedicated fault reporting via open-drain nFAULT pin.

FAQ

What is the maximum recommended PCB copper thickness for the power pads of IRSM636-015MB?

The power terminals (P, N, V_U, V_V, V_W) require ≥2 oz (70 µm) copper on inner layers and ≥3 oz (105 µm) on outer layers to sustain 15 A continuous current with ≤25 °C temperature rise. Thermal vias spaced ≤2 mm apart under each pad are mandatory for effective heat transfer to internal planes.

Does IRSM636-015MB support 100% duty cycle operation on high-side IGBTs?

No. Due to bootstrap-based high-side supply architecture, sustained 100% duty cycle is not supported. Maximum high-side on-time is limited by bootstrap capacitor recharge time; typical practical limit is 95% at 15 kHz with 22 µF ceramic capacitors and <10 Ω gate resistance.

Can the nFAULT pin be directly connected to an STM32 microcontroller GPIO?

Yes. The nFAULT pin is an open-drain output with 20 mA sink capability and 5.5 V absolute maximum rating. It can be pulled up to 3.3 V with a 4.7 kΩ resistor and connected directly to an STM32 GPIO configured as external interrupt input with pull-up enabled.

What is the minimum required dead time between complementary IGBT gate signals?

Infineon specifies a minimum 1.2 µs dead time to prevent shoot-through. This value accounts for propagation delay mismatch (<150 ns), gate driver rise/fall times (<100 ns), and IGBT turn-on/turn-off dispersion. Using less than 1.2 µs risks simultaneous conduction and destructive current spikes.
